ATEX

New ATEX Directive doesn’t affect hoses

The ATEX 94/9/EC regulation has been removed and replaced by a new Directive 2014/34/EU.  

The modifications clarify the manner of notification of authorities, implementation of member state relationships, and the responsibilities of distributors and retailers. 

As a hose manufacturer, this new directive has no impact on us. 

The directive 2014/34/EU relates to equipment and protective systems intended for use in potentially explosive atmospheres. It applies to equipment capable of causing an explosion through its own potential sources of ignition. Hoses and hose assemblies do not fall within the scope of this directive since they don’t have own potential sources of ignition. As a result, CE branding and ATEX logo branding are forbidden on hoses and hose assemblies.
The technical specification CEI/TS 60079-32-1:2013, Explosive atmospheres - Electrostatic hazards, guidance, provides standard recommendations for the control of static electricity.

This technical specification points out the conditions to use hose assemblies in ATEX areas for liquid and pneumatic transfers:

• All steel helices and copper wires must be connected to the couplings.
• The hose must be permanently grounded to earth.

For liquid transfer, the requirements depend on the conductivity of liquids. However, if the electrical resistance of tube is less than 1 MΩ per length, the hose can be used to transfer all liquids (high, medium and low conductivity).
